Both Gametophyte and Sporophyte are
the two Generations of a plant
. Gametophyte: Gameto means gametes and phyte means plants. The generation of plants that forms gametes is called gametophyte. … Sporophyte: Sporo means spores and phyte means plants. The generation of plants that produce spores is called sporophyte.
What is gametophyte and sporophyte?
Both Gametophyte and Sporophyte are
the two Generations of a plant
. Gametophyte: Gameto means gametes and phyte means plants. The generation of plants that forms gametes is called gametophyte. … Sporophyte: Sporo means spores and phyte means plants. The generation of plants that produce spores is called sporophyte.
What is called gametophyte?
Gametophyte, in plants and certain algae,
the sexual phase (or an individual representing the phase) in the alternation of generations
—a phenomenon in which two distinct phases occur in the life history of the organism, each phase producing the other. The nonsexual phase is the sporophyte.
What is a gametophyte Class 11?
The gametophyte is
the sexual phase in the alternation of generations of plants and a few algae
. This stage produces gametes that undergo alternation of generations. It is a haploid phase producing the zygote from which sporophytes arise.
What is a gametophyte for kids?
Fig 4 the fully grown gametophyte is
a small flat plant mostly just one layer of cells
. Fig 5 after an egg cell near the centre of the gametophyte was fertilized, it grows into a fern plant with leaves and roots. The alternation of generations is an important concept in the evolution of plants.
What is difference between sporophyte and gametophyte?
| Difference Between Gametophyte and Sporophyte | Sporophytes Gametophytes | Sporophytes have two sets of chromosomes Gametophytes have a single set of chromosomes | Sporophytes reproduce asexually Gametophytes produce sexaully |
|---|
What is difference between sporophyte and gametophyte phase?
The plants’ haploid phase is called the gametophyte, and the diploid phase is called the sporophyte. Offspring alternate from
diploid sporophytes to haploid gametophytes
and back again in generations. This means plants generate two different kinds of plants with the same genetic material.
What is the other name of female gametophyte?
The female gametophyte is also commonly called
the embryo sac or megagametophyte
. The male gametophyte, also called the pollen grain or microgametophyte, develops within the anther and consists of two sperm cells encased within a vegetative cell (Gifford and Foster, 1989).
What is a gametophyte generation?
The sexual phase, called the gametophyte generation,
produces gametes, or sex cells
, and the asexual phase, or sporophyte generation, produces spores asexually. In terms of chromosomes, the gametophyte is haploid (has a single set of chromosomes), and the sporophyte is diploid (has a double set).
What are the two types of gametophytes?
These spores develop into two distinct types of gametophytes;
one type produces sperm and the other produces eggs
. The male gametophyte develops reproductive organs called antheridia (produce sperm) and the female gametophyte develops archegonia (produce eggs).
Why gametophyte is called so?
The gametophyte is
the sexual phase in the life cycle of plants and algae
. It develops sex organs that produce gametes, haploid sex cells that participate in fertilization to form a diploid zygote which has a double set of chromosomes.
What is Protonema Class 11?
Hint: Protonema is a creeping, green, branched, and often filamentous stage of the growth process. It is a haploid, autonomous, gametophytic stage of the moss life cycle. Complete answer: A protonema is a
thread-like chain of cells that forms the gametophyte’s earliest stage of growth in the life
cycle of mosses.
What is Prothallus Class 11?
Prothallium or prothallus is typically
the gametophyte stage within the life cycle
. The prothallus develops from a germinating spore. Prothallium is a short-lived and inconspicuous heart-shaped structure typically 2–5 millimeters wide, with a diversity of rhizoids (root-like hairs) growing underneath.
What is the difference between gamete and gametophyte?
The key difference between gamete and gametophyte is that
the gamete is the sex cell produced by the sex organs of the gametophyte
while the gametophyte is the male or female haploid stage of the life cycle of certain organisms including plants and algae.
What is the function of a gametophyte?
A major function of the gametophyte generation is
to produce haploid gametes
. Fusion of the egg cell with the sperm cell gives rise to the sporophyte, thereby completing the life cycle (Raven et al., 1992). In many lower plants, gametophytes are the dominant and free-living generation.
Which plants are gametophyte dominant?
Nonvascular plants include
mosses, liverworts, and hornworts
. They are the only plants with a life cycle in which the gametophyte generation is dominant.
